The HPSG Project conducts its activity under the umbrella of CSLI's
Linguistic Grammars Online Project,
which has developed various large-scale HPSG grammars. These
grammars have blended into HPSG a number of features taken
from work in Berkeley Construction Grammar. The resulting
synthesis
is the emerging framework of Sign-Based Construction Grammar
(SBCG), as developed in:

Information about Syntactic Theory: A Formal
Introduction, by Ivan Sag, Tom Wasow, and Emily Bender,
is available from
CSLI Publications. There is also an online instructor's manual by Bender, Sag,
and Wasow for this textbook.

DELPH-IN
Project. Computational linguists of research sites world-wide have
joined forces in a collaborative effort aimed at deep linguistic
processing of human language. The goal is the combination of
linguistic and statistical processing methods for getting at the
meaning of texts and utterances. The partners have adopted Head-Driven
Phrase Structure Grammar (HPSG) and Minimal Recursion Semantics (MRS),
two highly advanced and influential models of formal linguistic
analysis. They have also committed themselves to a shared format for
grammatical representation and to a rigid scheme of evaluation, as
well as to the general use of open-source licensing.

DeepBank The
DeepBank project has the goal of annotating the one million words of
1989 Wall Street Journal text (the same set of sentences annotated in
the original Penn Treebank project) with the English Resource Grammar,
augmented with a robust approximating PCFG for complete
coverage. DeepBank contains rich linguistic annotation on both
syntactic and semantic structures of the sentences and is available in
a variety of representation formats.

FUB German Grammar
Group Stefan Mueller's group in Berlin has developed numerous
resources for the HPSG-based analysis of German and various other
languages. These are based on
the TRALE
System, developed at the University of Tuebingen.
